1. If I claim a patent at level 2, and then later claim a patent at level 3 do I move my marker off of level 2 and up to level 3?
No, you leave the older one there. Other, less developped companies still have to pay to use your earlier patent.
2. If I claim a project that is level 2 and I have level 2 technologies but my opponent owns patents at level 3 do I pay them?
No, why would you. You don't have level 3, so you can't use "his" technology.
3. Also, do luminary abilities apply to themselves? Like can Edison himself ignore the patent cost?
Yes. "His company" includes him. And he hastn't been exhausted earlier.
